FRANK W. HEWITT, 0F ARLINGTON, MASSACHUSETTS, ASSIGNOR T0 SIMPLEX ELECTRIC HEATING COMPANY,

'lION' OF MASSACHUSETTS.

To all whom it may concern."

Be it known that I, FRANK W. Hnwrrr, a citizen of the United States, residing at Arlington, county of Middlesex, State of Massachusetts, have invented an "Improvement in Electric Ranges, of which the following description, in connection with the. accompanying drawing, is a specification, likecharacters on. the drawing representing likeparts.

This invention relates to the construction cooking plates are associated with a baking ovenand usu-. ally with other heating compartments.- he main object of the invention is to pro+ vide a construction in which the various switches controlling the various heating units,

terminals or other electric distributing fittings may all be asse nr box which may be put.- in place after assembling and to which ac cess may be readily had when in place.

The object of the invention is further to rovide adistributing box so positioned and ocated that the circuit wires leading to the heating units of the oven or other heating.

compartment maypass directly through the side wall thereof and the circuit wires leadcan.

lates may pass directly ing to the cooking box to the cooking a from the distributing plates.

The invention also has for its object to provide a distributing box located directly against the 'side wall of the oven and provided with an opposite side closure opening over the cooking plates so that ready access may be had to the interior of the distributing box upon the opening or removing of the closure.

The inventionalso has for its object to I provide for the location of all the controlling switches centrally ofthe range in 'a vertica row.

These and other objects and features of the invention will appear more fully from the accompanyin description and drawings and will be particularly pointed out" in the claims.

An electric range embodying this inventlon comprises essentially a horizontal table .6 and a vertical oven. In the table are The oven 10 extends vertically with re-' spect to the table 6 and may be and preferably is mounted on top of the table and is provided with one or more, in the form illustrated with two, ovens or heatin compartments maybe arranged in vertlcal series as desired. As illustratin this feature a broiling oven 11 is shown a ove the main or baking oven 10 and provided with a single heating unit.

In this invention a distributing box is provided upon which are mounted the vafuses, terminals and other fittings requisite for distributing the electric current from the main line'to the various heating units. This distributin box is located' at the side of the vertical y arranged ovenor tier of heating compartments and at that side facing the cooking plates. This arrangement enables the circuit wires to lead directly from the distributing box through the sidewall of the ovens or heating comthe interior thereof. Thus these heating units may readily be disconne'cted and connected for repair or replacewiring in the oven is ThlS arrangelead ment and thus also the reduced to the minimum. ment also enables the circuit 'wires to directly from the distributing box through the wires leadr Patented June 1'7, 1919.

minimum. This arrangement also enablesthe main circuit wires to be brought directly into the distributing box from the back of the range through therear end of the dis-- tributing box and it also enables-if desired tributing box. v

It will thus be seen that a very compact the main line switch to be located in the disandsimple structure is provided in which the wiring in the range 1s reduced to the minimum and in which direct connections are made from the distributing box to all the The distributing box. isa narrow vertical structure being only of suflicient width to accommodate the necessary electrical fittings. This enables the switches for all the heating units to be arranged in a single vertical row centrally-of the range where ready access thereto may be had.

The distributing box being located at the side of the oven or heating compartments and facing the cooking plates enables a side closure to be provided which may be readily removed or swung down or aside in the space above the cooking plates so that at any time access may be readily had to the entire distributing box, and consequently to all' the various fuses, terminals and fittings 1nstalled thereon.

It will thus be seen that the distributing box may be madeup with the switches, fuses, terminals and all the wiring leading therefrom and inst'alledas-a single unit. greatly facilitates and consequently reduces the-cost of manufacture of the range. 1 The construction also enables any repairs or replacements readily to be made after the dis-.

' 12 and a front wall 13. The upper, lower and rear ends of the box may be and preferably are entirely open. When in position the ends may be closed subject to requirements of ventilation by adjacent portions of the range. As shown the rear end and the bottom end are left open while a warming oven 14 located on top of the broiler 11' at" tends-over and covers-the upper end of the distributing box. The precise construction of the upper, lower and rear ends of the tributing box is, however, not essential. It is essential however that it present the side wall 12, the front wall 13 and the removable closure atthe opposite side wall.

. This removable closure in the. form illus- -'trated is shown as a door 16 hinged at the bottom so that it may swing down over the cooking plates 7 exposing the entire interlor of the distributing box. This closure 16 is conveniently hinged to a plate 17 upstanding from the table 6 and it fits in beneath a plate tributing box extending rearwardly to the closure 16. But these are all details of con- A struction which may be varied as desired. a

The main feature is to provide a closure 16 which may be removed or swung aside from the distributing box over the cooking plates. The switches controlling the heating units are mounted on the front wall 13 of the distributing box. As illustrated the switches 20, 21, 22 and 23 control respectively the four cooking plates 7, the switches 24 and 25 control the lower and upper heating units respectively of the oven 10, and the switch 26 controls the heating unit of the broiler 11. Other connections may be installed on the front Wall 13 of the distributing box as desired and as illustrating this feature a receptacle 27 is shown to'which connection may be made with a flat iron, percolator, toaster or other device.

The distributing box when in place rests upon the table 6 against the side Wall of the oven or tier of heating compartments and is fastened securely but rem'ovably in place as bysuitable screws 28.

The various electrical fittings on the distributing box will be varied according to the particular requirements. Preferably as already pointed out the main circuit wires 29 and 30 enter through the back of the range "and through the open rear end of the distributing box and preferably also the main line switch 31 is mounted on'the side wall 12 A of the distributing box. This enables the range to be installed simply by connecting the main circuit to the terminals 32, 33. I

Fuses as required are mounted on the side wall 12of the distributing box. As illustrating this feature are shown the fuses 34 for the main line and the fuses 35 arranged in a vertical row for each heating unit.

The wires extending to the oven or vertically arranged heating compartments lead directly through the side wall 12 of the distributing box and through the adj a'cent side walls of the oven. In the case of the lower heating unitof the oven 10 an insulator 36 with threeopenings is provided and through these openings the wires 37, 38 and 39 extend to the heating unit inside the oven. A

bracket 40' is mounted on the side wall 12 of the distributing box and extends out adjacent the insulator 36. On this bracket are mounted binding posts 41, 42 and 43 to which the wires 39, 38 and 37 respectively lead, and from which the circuit wires lead to the corresponding switch 24. The con-' struction is -the same with respect to each oven or vertical heating compartment heating unit. Hence when it is desired to remove the oven heating unit all that is necessary is to disconnect the wires 37, 38 and 39 to the bracket 45 which connections extend to the broiler 11 shown in a compartment above the baking oven. I

It will be understood that the fuses, terminals and other fittings'may be arranged as required uponthe side wall 12 of the distributing box and that various other fittings as required'may' be arranged upon this side wall. This construction enables all the electric fittings required to be mounted upon the the distributing tal table provided distributing box and the connections to be made to the switches, receptacles or other devices on the front wall of the distributing box so that the entire electric mechanism ex; cepting the direct connections with the,heat-' ing units. may be assembled and mounted upon the distributing box before it is placed in positionrin the range and so that after the distributing box is in position in the range ready access may be had through the side of box to all of these devices and at a position, namely over the cooking plates, where this access enables these devices to be repaired, replaced, connected and disconnected or changed or added to as required.
